Abstract: in a full-thickness defect of a lower eyelid, as a general rule, is mandatory to reconstruct the tarsal plate and the conjunctiva. the reason is that the orbicularis oculi muscle cannot support the effects of gravity and/or cicatricial contracture. the abscense of conjunctiva provokes corneal lesions. therefore, a chondromucosal graft is obligatory. this research has been performed in 20 albino rabbits to evaluate the possibility of tarsal plate reconstruction with conchal cartilage graft without mucosa. the results of the research have demonstrated, by different histological biopsies, that the raw surface of the perichondrium is epithelized with a new conjunctiva (neoconjunctiva). these findings results are very important since they modify the principles of the lower eyelid reconstruction. we have confirmed that it is not necessary to reconstruct the conjunctive and there are regeneration from the sorrounding mucosa.

Abstract: Objective: Eyelids and conjunctiva, which are composed of cutaneous, mucosal and stromal tissues, may develop various pathologies. Histopathological diagnosis of the lesions located in these anatomical regions is crucial for determining the optimal therapeutic modality and protection of ocular functions.Material and Methods: In this retrospective study, the clinical and histopathological features of neoplastic lesions located on the eyelids and the conjunctiva diagnosed at the Department of Pathology in Karaelmas University Faculty of Medicine between the years of 2003 and 2008 were reviewed and evaluated.Results: A total of 127 cases were included to the study. 84,2% of the lesions in our case series were located on the eyelids. 69,1% and 30,9% of these eyelid lesions were benign and malignant, respectively. 15,8% of the lesions were conjunctival. 95% of the conjunctival lesions were benign, while 5% were malignant. The most common benign lesions of the eyelids were squamous papillomas (20,3%), while the most commonly observed malignant neoplasm was basal cell carcinoma (57,6%). Most of the benign conjunctival lesions were melanocytic nevi (57,9%), while only one case was diagnosed as in situ squamous cell carcinoma.Conclusion: Basic histopathological analyses of the periorbital lesions were performed in this study. The most commonly encountered malignant lesions of the eyelids and conjunctiva were basal and squamous cell carcinomas.

Abstract:
Ectropion is an outward turning of the eyelid margin, as a result the conjunctiva is permanently irritated, thickened and dry. Since the lacrimal puncta are moved away from the eyeball, the tear elimination is difficult, tears are always present. Materials and Methods: This study includes patients suffering from senile ectropion, who were treated surgically at Polyclinic “SHOSHI” in Prishtina. Our study includes 19 patients suffering from senile ectropion, out of which, 17 were older than 75 years old and in those patients the ectropion was preset on both lower eyelids, while 2 patients were under 75 years old and the ectropion was present only on one side lower eyelid. Prior to surgery, patients have undergone laboratory examinations. The surgery was performed under local anesthesia. The suturing was done in three layers using 6.0 vicryl sutures. No operative or post-operative complications were encountered. Purpose: The purpose of this case report study is to show the success of the surgical treatment of ectropion, a procedure that is mainly performed so the tear elimination is enabled, and there are no tears present constantly. Conclusion: In old patients where the eyelid is turned outwards its margin, conjunctiva is constantly irritated, thickened and dry, the best method of treatment is the surgical treatment, making it possible for the tears to drain properly.

Abstract: The results showed that HPV DNA was present in 8 CSCC samples (22%); HPV16 was the sole type detected. Significant association was found between HPV detection and the limbus tumor subtype (p = 0.03). All the samples were non-metastatic squamous cell carcinoma.The HPV presence in CSCC from Mexican patients is not a common event.Squamous cell carcinoma (SCC) is the most common neoplasm of the conjunctiva [1]. The etiology of cancer of the conjunctiva appears to be multifactorial; several risk factors have been identified, such as smoke, Human immunodeficiency virus (HIV) infection, Ultraviolet (UV) light, history of pterygium, or Human papillomavirus infection (HPV) [2,3]. However, the reports on HPV and conjunctival neoplasms are controversial. Some studies have reported a heterogeneous prevalence of high-risk HPV types, suggesting that only a subset of cases can be attributed to these viruses [4,5]. Differences in detection methods, populations, or geographic distribution could contribute to the variation in HPV infection rates in Conjunctival Squamous Cell Carcinoma (SCC)[6-12]. HPV is considered the main etiologic agent in proliferative ocular surface, lachrymal sac lesions, and pterygium worldwide, and it is has been suggested that HPV types 16 and 18 play a critical role in the oncogenesis of conjunctival cancers [13-17].HPV are a group of host-specific DNA viruses with oncogenic subtypes that have been shown to act as carcinogens in the development of Cervical Cancer (CC), anogenital, head and neck, and CSCC [18,19]. While the E6 oncoprotein, encoded by HPV16 or HPV18, is known to bind the cancer gene product p53 and to promote its degradation, the E7 oncoprotein binds to the retinoblastoma cancer gene product pRB and results in E7-induced pRB inactivation. The E5 virus protein cooperates with E7 to transform cells and enhances the ability of E7 to induce proliferation, and with E6, to immortalize cells [20]. Preclinical and clinical studies suggest that the ad

Abstract: purpose: to identify mycobacterium leprae in ocular conjunctivae and evaluate conjunctival bacilloscopy as leprosy diagnosis and follow-up test. methods: we used the superior tarsal conjunctiva scraping technique in 52 newly diagnosed leprosy patients between july and september 2004 at the "oculistas associados de brasília", in brasília, df, brazil, and compared the conjunctival bacilloscopy with skin bacilloscopy. results: both the conjunctival bacilloscopy index (cbi) and skin bacilloscopy index (sbi) showed correlation since pearson's r and cohen kappa measure of agreement were respectively 76.3% (p<0.01) and 0.615 (p<0.01). pearson chi-square also evidenced the correlation (p<0.01). comparison of cbi and sbi (17 cases of positive cbi out of 26 sbi) gives a sensitivity of 65.4% (ci95% - 0.519-0.690); 25 cases of positive cbi out of 26 cases of negative sbi give a specificity of 96.2% (ci95% - 0.826-0.998); positive predictive value of 94.4%; negative predictive value of 73.5%, and accuracy of 80.8%. likelihood ratio was 17. mean time to eliminate the bacilli from conjunctiva was 5 months (ci95% - 3.57-6.43). conclusion: we suggest the use of conjunctival bacilloscopy in addition with skin bacilloscopy to confirm leprosy diagnosis. conjunctival bacilloscopy may also be useful for treatment follow-up in leprosy.
